feat: improve display format of literals

[fuyufjh]

What's changed and what's your intention?

Improve display format of literals.

Use fmt::Display instead of fmt::Debug, except that string literals are wrapped with single quotation marks (e.g. 'foo').

Why implement Display instead of ToString?

https://doc.rust-lang.org/std/string/trait.ToString.html

This trait (ToString) is automatically implemented for any type which implements the Display trait. As such, ToString shouldn’t be implemented directly: Display should be implemented instead, and you get the ToString implementation for free.

Debug -> Display, I think
